13. Morfologia, imuno-histoquímica e aspectos ultraestruturais das células imunorreativas à insulina no intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) adulto / Morphology, immunohistochemistry and ultrastructural aspects of insuline immunoreactive cells in small intestine of the opossum Didelphis aurita (WIED-NEUWIED, 1826) adult
Esta pesquisa teve como objetivo geral descrever os aspectos morfológicos, histoquímicos e imuno-histoquímicos do intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) adulto, bem como as características ultraestruturais dos grânulos secretores de células imunorreativas à insulina nesse animal. A biogênese dos grânulos insulínicos e a s

14. Intrauterine growth restriction in an experimental model of pregnant rats and their effects on insulin cellular receptors / Modelo experimental de restrição de crescimento intrauterino em ratas prenhes e suas repercussões em receptores celulares de insulina
Intrauterine growth restriction (IUGR) limits appropriate fetal development increasing morbidity and perinatal mortality. Adaptive mechanisms in fetal IUGR may leave to endocrine and metabolic alterations that could explain the occurrence of diseases in adulthood. The aim of this study was to evaluate whether experimental IUGR by uterine artery ligation caus

15. Camallanus tridentatus (Drasche) (Nematoda: Camallanidae): new taxonomically important morphological data
Camallanus tridentatus is redescribed on the basis of the examination of specimens obtained from the stomach, caeca and intestine of the naturally infected arapaima Arapaima gigas (Schinz) from the Mexiana Island, Amazon River Delta, Brazil. Data on the surface morphology of adults inferred from confocal laser scanning and scanning electron microscopical obs

16. Morphology of the alimentary canal of the gecko Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae) / Morfologia do tubo digestivo da lagartixa Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae).
Hemidactylus mabouia is the gecko species more thoroughly distributed in Brazil, being common in anthropic atmospheres, what turns easy its use as model for study of the reptiles. Likewise, aiming at to describe morphologically the alimentary canal of H. mabouia, 17 adult specimens were used, being collected fragments of the esophagus, of the oesophagogastri

17. Synthesis, characterization of biocompatibility and evaluation of bioadhesion of n-carboxymethylchitosan nanoparticles in hybrid networks with poliacrylic acid / Síntese, caracterização e avaliação da biocompatibilidade e bioadesão de nanopartículas de n-carboximetilquitosana em redes híbridas com ácido poliacrílico
Chitosan nanoparticle complexes with polyacrylic acid have been used in nanotechnology, as they improve pharmacological activity, in chemical and biological terms, and in particular, increase drug bioavailability. The aim of this work is to evaluate the biocompatibility and bioadhesion of N-carboxymethyl derivatives of chitosan (N-CMC) with in situ polymeriz

18. Influence of egg pre-storage heating period and storage length on the digestive tract of newly-hatched broiler chicks
An experiment was carried out to evaluate the effect of different heating times of settable eggs of Cobb 500® broiler breeders before submitting them to different storage periods on body weight, digestive tract organ weights, and intestinal mucosa morphology of newly-hatched chicks. Settable eggs were distributed in a completely randomized experimental desi

19. Efeitos da oxigenoterapia hiperbárica após isquemia hepática segmentar normotérmica e reperfusão, em coelhos:: Avaliação bioquímica, morfológica e da microcirculação hepática pelo ultra-som contrastado
Interruption of blood flow to an organ or tissue (ischemia) and subsequent reperfusion lead to an acute inflammatory response that may cause significant cellular damage and organ dysfunction. It is called ischemia/reperfusion injury. Hepatic ischemia/reperfusion injury is characterized by circulatory and metabolic derangements, liver dysfunction and tissue d

20. Computational histomorphometry of broiler chickens organs submitted to two distinct feeds: chelated minerals and not chelated minerals diet. / Morfometria computacional de órgãos de frangos de corte submetidos a duas dietas distintas: suplementação mineral quelada versus suplementação mineral tradicional
This research studied the influence of chelated minerals in broilers chickens nutrition as well as the constitution and morphology of bone, liver and intestine of these animals, by means of the utilization of mathematical and computational techniques including computer vision, pattern recognition and statistical analysis. Additionally, the immunological resp

21. Observations on Eimeria species of Dasyprocta leporina (Linnaeus, 1758)(Rodentia: Dasyproctidae) from the state of Pará, North Brazil
Redescriptions are given of the mature oocysts of Eimeria aguti Carini 1935, E. cotiae Carini, 1935 and E. paraensis Carini, 1935, in the faeces of five specimens of the rodent Dasyprocta leporina (Rodentia: Dasyproctidae) from the state of Pará, North Brazil. New information is provided on the sporulation time of these parasites and the prepatent period in

22. Metamorphosis in the midgut of bees : proliferation or cellular migration? / Metamorfose do intestino medio de abelhas : proliferação ou migração celular?
Bees are holometabolus insects, since they present complete metamorphosis. During the metamorphosis of the insects the gut is completely remodeled. Few studies emphasize aspects of the renewal of the epithelium of bees midgut during metamorphosis. Studies that describe digestive cell proliferation are lacking in images of mitosis. This research is a contri

23. Histology of the digestive tract of surubim-pintado (Pseudoplatystoma coruscans - Agassiz, 1829) / Histologia do trato digestório do surubim-pintado (Pseudoplatystoma coruscans - Agassiz, 1829)
Pintado (Pseudoplatystoma coruscans), also commonly called surubim, is one of the most appreciated fish by the Brazilian consumer market, due to the excellent filet quality. However, works on the morphology of their digestive tract are scarce. In this work, the histological description of the esophagus, stomach and intestine of pintado, seeks to contribute a
